An amusement park ride consists of airplane-shaped cars attached to steel rods. Each rod has a length of 15m and a cross-sectional area 8.00cm^2. Take Young's modulus for steel to be Y= 2.0 x 10^11 Pa.
How much is the rod stretched (change in length of) when the ride is at rest? Assume that each car with two people seated in it has a total weight of 1900 N.
Answers: 1
is the stretching in the rod
